Rapid Disk Resync Disk Mirroring - NEC Express5800/320Ma Administrator's Manual

In addition, your Express5800/320Ma system uses other drivers developed by NEC
Solutions (America), Inc. These drivers allow the system and all PCI devices to
integrate with the ASN, and provide management of all system devices and device
fault-tolerance.
ASN integration provides:
•
Automatic reporting of device failures to the NEC Technical Support
•
Notification to you by the NEC Technical Support when a device fails
•
Inventory reporting to the NEC Technical Support that lists all PCI devices in the
system
•
Comprehensive debug information about all devices in the system for use by the
NEC Technical Support in troubleshooting your system
Management of PCI devices includes:
•
On your Express5800/320Ma system, hot-plug support alerts the plug-and-play
manager to bring a device into service or take it out of service. You can initiate
bring-up or bring-down from ftSMC. Hot-plug support also initiates discovery of
newly attached or removed devices.
•
Display of information so that you know whether removing a device will
compromise the system. The drivers can set LEDs and values in ftSMC that let you
know whether you can safely remove a component.
•
Display of information about the device in ftSMC.
Device fault-tolerance includes:
•
Automatic restart of failed devices. The device will be restarted after transient
faults, until it falls below its mean-time-between faults (MTBF) threshold.
•
Tracking the MTBF of a device and management of the device when it experiences
faults. You can set parameters to take the device out of service when the device
experiences an unacceptable MTBF. You can configure the rules for MTBF
management.

Rapid Disk Resync Disk Mirroring

Rapid Disk Resync (RDR) disk-mirroring technology provides faster resynchronization
of mirrored disks than other mirroring methods after transient failures or when a single
N O T E
You must remove the CPU- I ⁄ O enclosure from the
system in order to remove a PCI adapter.
